AICodingFlow: Skill for Claude Code

.github/skills/security-review-pr/SKILL.md

security-review-pr is a skill for Claude Code, Codex from Terry-Mao/AICodingFlow. It costs 66 tokens per session (913 once invoked), scanned A, original, MIT.

A security-focused supplement for reviewing a code pull request, which is a proposed set of changes to a shared codebase. It checks changed code and configuration for issues such as unsafe input handling, weak access controls, exposed secrets, and risky dependencies.

In plain words
What is it for?
Use it alongside the main pull-request review for code or mixed changes, especially when the changes handle user input, authentication, authorization, secrets, or dependencies.
Why use it?
It helps catch security problems that a general code review may miss. Its findings are added to the project’s existing review report instead of creating a separate format.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security-review-pr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Review PR Skill

Audit the current pull request for code-level security concerns and fold any findings into the same review.json produced by review-pr.

Required Contract

Read .agents/contracts/review.md and follow it exactly. This skill is a supplement to review-pr; it must not create a separate report, change the review.json schema, loosen diff-line targeting, post to GitHub, call external security APIs, or regenerate snapshots.

When To Apply

  • Apply on code and mixed PRs whenever review-pr is applied.
  • Do not apply on spec-only PRs handled by review-spec.
  • Skip the skill when no changed file introduces code or configuration touching the concerns below.
  • Do not duplicate findings the base review-pr pass will already raise.

Security Concerns

Evaluate each changed hunk against these concerns. Treat the list as a checklist, not a ceiling; flag other clearly security-relevant issues when they appear.

Input Validation And Untrusted Data

  • User-supplied or network-supplied input used without validation, length limits, or type checks.
  • Deserialization of untrusted data, including pickle, yaml.load, eval, Function, or parsed JSON flowing into commands.
  • Path traversal from user input concatenated into filesystem paths without normalization or an allowlist.
  • SSRF from user-controlled URLs passed to outbound HTTP clients without scheme or host restrictions.
  • Unbounded resource use driven by untrusted input.

Output Encoding And Sanitization

  • Untrusted data interpolated into SQL, shell commands, HTML, Markdown, log lines, or URLs without proper encoding or parameterization.
  • Use of shell=True, string concatenation into process execution, or raw SQL strings.
  • Rendering user-supplied Markdown or HTML without sanitization.

Authentication And Authorization

  • Missing or weakened authentication on new endpoints, RPC handlers, workflow triggers, or CLI commands.
  • Authorization checks that trust client-supplied identifiers instead of the authenticated principal.
  • Permission checks removed or made more permissive without clear justification.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
